Patented Mar. 11, 191 3.

1909. Serial Naeeama To all whom it may concern Be it known that I, Q'rro llTANTlUS, a subject of the Emperor of Germany, and a resident of the city of Philadelphia, County of Philadelphia, State of Pennsylvania, United States of America, have invented certain new and useful Improvements in Continuous-Operating Centrifugal Machines, of which the following is a specification. I

My invention relates to improvements in operating centrifugal machines, and has for one of its objects to produce a centrifugal machine that may be continuously operated and be prevented from vibrating when the material is not evenly charged thereto or discharged therefrom.

Another object is to produce a machine in which the basket may be cone-shaped or curt-ed. Y

Other objects will appear from the following description.

The invention is fully set forth in the'following description taken in connection with the accompanying drawing which forms part of this application and in which the same reference character indicates the same part in the several views.

Referring to the drawing, Figure 1 is a vertical section through the center of the machine. Fig. 2 1s a section on line 2 of Fig. 1. Fig. 8 13 an enlarged detail view in cross sectlon of the wall of the basket. Fig.

4: is a detail view.

The part marked 1 on the drawing represents an electric motor or other source of power which is connected tothe driving shaft 2 of the centrifugal machine. This shaft is mounted in bearings 3 and 4;.

'5 isa spider which is secured to the shaft- 2 and rotates therewith.

6 is a fly wheel rigidly secured to the arms of the spider.

7 is a basket the wall of which is preferably in the shape of a frustum of a cone or curved. This basket consists of a perforated plate '1' strengthened on the outside by hoops or rings 7. Secured to the inside of this plate is a wire screen 7. The arms of the spider pass through openings 7 in the wall of the basket. The top of the basket may be closed by an annular plate T therein. This of the basket, forming an inwardly projecting flange, or may be a separateplate secured thereto. I use this plate for the purpose hereinafter stated. I

S is a member located inside of the basket and consists of an inclined annular-wall 8 and a flat top or cover S The wall -8 is at a greater inclination than the wall of the basket so that there is a space A between the inner and outer walls of the basket and an outlet passage B between the lower edge of said wall 8 and the inner wall of the basket. Connected to this top'orcover is a sleeve 8 ,which surrounds the shaft 2. This sleeve is provided with a collar 8 to which is connected the inner end of an ad justing lever 9. The walls of the member 8 are provided with slots 8 through which project the arms of the spider 5. by said arms of the spider are plates 10 which cover the opening 8 said plates being movable in suitable guides 11.

closes the movable parts of the machine. This casing has anoutlet 12 in the lower side thereof and an opening 12 in the top. The bottom of this casing is closed by an annular plate 13 which has an annular opening 14: in the center thereof, the inner edges of this bottom being upturned as shown. The lower end of. the basket projects through this opening but it is free to rotate therein.

15 is a hopper secured to the bottom of the casing and provided with an outlet 16.

17 is a supply tank located above the machine and provided with an outlet pipe 18. The lower end of said pipe projects through the opening 12 and extends over the top 8 of the member 8.

the member 8 is raised or lowered so that the opening B is adjusted to the proper size for the material being separated. The raising of the member 8 1s accomplished by the lever 9. Theslot member 8 permits it to have vertical movement relative to the arms of the spider, the openings in the wall being closed by the slide 10 which is fastened to the arms of the spider. When the opening is properly adjusted, the motor 1 is put in motion and the shaft 2 is rotated. The spider being connected to the shaft, the rotation of the shaft will cause rotation of the member 8,

T and thetly wheel 6. The ma torial to be separated having been placed in 'Carried 12 is an outer jacket or casing which in- 8 in the wall of this the supply tank 17 is fed through thepipe 18 onto the top 8 of the member 8. The

'. machine beingrotated at high speed, theedge of the basket it will be thrown by centrifugal force from the basket against the inner Wall of. the hopper 15 and be discharg'ed through the opening 16. The adjustment of the member 8, ofcourse, may be .2 made during the'running of the machine.

I The inclination of the wall of the basket will vary and depend on the friction of the material being separated. The fly wheel is made very heavy and weighs from twenty to fifty times asmuch as the amount of 'solids retained on the inside of the basket of the machine. This is to prevent vibra- .tions in themachine when the material is not evenly -charged or discharged orwhen unevenly distributed on, the side of the basket. The uneven distribution of the material will amount only to a small percent- .age of the total rotating Weight in the fly wheel 6. l I

By providing the basketwit-h the cover 7 I may feed the liquor from the "tank 17 in such quantity that said liquor will fill the space A between the wall. of the basketand the wall of the member 8, and bank up at 40 the upper end of this space. The cover or .plate 7 will hold the banked up material within the basket and prevent it from being thrown out over the upper edge of the basket by centrifugal force; Then, by regulating the amount of flow of liquor supplied to the basket I can keep the liquor in the space A up to a certain predetermined point. The weight ofthe liquor in this space tends -to force the solids through the opening B and the amount of banked up material can be varied so as tovary the speed at which to force out the solids through the opening B,

and-inthis Way the dryness of the material can be varied.

Instead of making the Wall of the basket and the member 8 inclined on a straight line,

the same may be curved with their lower edges converging as previously described;

as shown in dotted lines, Fig. 1. As any changes could be made in the ,ab'o've construction. and many apparently widely dih'erent embodiments of my invention could be made without departing from thescope thereof, I intend that all matter as contained in the above description or shown basket.

in'the accompanying drawing shall be interpreted as" illustrative and not iii a limiting sense. I desire it also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scopeof the invention, which, as a matter of language, might be said to fall therebetween. .1 Having now described my invention, What I claim asnew and desire to secure by Let'- ters Patent is:
